Collecting

For the first week of material collection events are picked up at the school 850 kg of paper and 305 kg of rags which represented 55% of total collection for 14 days. How many kilograms of secondary raw materials were handed over totally?

Correct answer:

x =  2100 kg

850+305 = 0.55 x

850+305 = 0.55•x

0.55x = 1155

x = 2100
